Multi-view display

Abstract

A display device includes a first display screen operable to display a first image. A second display screen is operable to display a second image, wherein the first and second display screens overlap, and wherein the second display screen is further operable to display the second image for viewing from a first viewing angle and contemporaneously for reducing visibility of the second image from a second viewing angle.

1 . A display device comprising:
 a first display screen operable to display a first image; and   a second display screen operable to display a second image, wherein said first and second display screens overlap, and wherein said second display screen is further operable to display said second image for viewing from a first viewing angle and contemporaneously for reducing visibility of said second image from a second viewing angle.   
     
     
         2 . The display device of  claim 1 , wherein said second display screen is further operable to display a third image, and wherein said second display screen is further operable to display said third image for viewing from said second viewing angle and further for reducing visibility of said third image from said first viewing angle. 
     
     
         3 . The display device of  claim 2 , wherein said second and third images are interlaced. 
     
     
         4 . The display device of  claim 1  further comprising:
 an optical component operable to reduce visibility of said second image from said second viewing angle, and wherein said first optical component is further operable to reduce visibility of a third image from said first viewing angle. 
 
     
     
         5 . The display device of  claim 4 , wherein said optical component is disposed between said first and second display screens. 
     
     
         6 . The display device of  claim 4 , wherein said optical component is selected from a group consisting of a privacy film, an image directing film, an optical directing film, and a lens including a lens stripe pattern. 
     
     
         7 . The display device of  claim 1  further comprising:
 a component operable to enable viewing of said first image from said first and second viewing angles. 
 
     
     
         8 . The display device of  claim 7 , wherein said component is selected from a group consisting of a diffuser and a refractor. 
     
     
         9 . A display device comprising:
 a first display screen operable to display a first image; and   a second display screen operable to display a second image, wherein said first and second display screens overlap; and   an optical component disposed between said first and second display screens, wherein said optical component is operable to enable viewing of said second image from a first viewing angle and contemporaneously operable to reduce visibility of said second image from a second viewing angle.   
     
     
         10 . The display device of  claim 9 , wherein said optical component is selected from a group consisting of a privacy film, an image directing film, an optical directing film, and a lens including a lens stripe pattern. 
     
     
         11 . The display device of  claim 9 , wherein said second display screen is further operable to display a third image, wherein said optical component is further operable to enable viewing of said third image from said second viewing angle, and wherein said optical component is further operable to reduce visibility of said third image from said first viewing angle. 
     
     
         12 . The display device of  claim 11 , wherein said second and third images are interlaced. 
     
     
         13 . A display device comprising:
 a first display screen operable to display a first image; and   a second display screen operable to display a second image for viewing from a first range of viewing angles, wherein said second display screen is further operable to display a third image for viewing from a second range of viewing angles, wherein said second and third images are interlaced, and wherein said first and second display screens overlap.   
     
     
         14 . The display device of  claim 13 , wherein said second range of viewing angles includes at least one viewing angle which is different from said first range of viewing angles. 
     
     
         15 . The display device of  claim 13 , wherein said second and third images are displayed using a respective set of directional pixels. 
     
     
         16 . The display device of  claim 15 , wherein a first set of directional pixels used to display said second image is operable to reduce visibility of said third image from said first range of viewing angles. 
     
     
         17 . The display device of  claim 15 , wherein a second set of directional pixels used to display said third image is operable to reduce visibility of said second image from said second range of viewing angles. 
     
     
         18 . The display device of  claim 13  further comprising:
 an optical component operable to reduce visibility of said second image from said second range of viewing angles, and wherein said optical component is further operable to reduce visibility of said third image from said first range of viewing angles. 
 
     
     
         19 . The display device of  claim 18 , wherein said optical component is disposed between said first and second display screens. 
     
     
         20 . The display device of  claim 18 , wherein said optical component is selected from a group consisting of a privacy film, an image directing film, an optical directing film, and a lens including a lens stripe pattern. 
     
     
         21 . The display device of  claim 13  further comprising:
 a component for enabling viewing of said first image from said first and second ranges of viewing angles. 
 
     
     
         22 . The display device of  claim 21 , wherein said component is selected from a group consisting of a diffuser and a refractor.
